COKE-OVEN-DISCHARGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 775,21 1, dated November 15, 1904.

Application filed March 17, 1904. Serial No. 198,562. (No model.)

To fr/Z 'IN1/mt it ntfty concern:

Be it known that I, ANDREW JACKSON Doss, a citizen of the United States of America, residing at Switchback, in the county of Mc- Dowell, in the State of VeStVii-ginia, have invented certain new and useful Improvements in Ooke-Oven-Discharg'ing Machines,of which the following is a specification.

This invention relates to a coke-puller designed to be operated by a machine for pulling coke from coke-ovens, and it is particularly adapted for discharging' coke from beehive coke-ovens.

In the manu facture of metallurgical coke the oven known as the i beehive oven, so called because of its dome-shaped form, has been generally adopted, being' found to give the best results. In the burning' of the coal the coke is produced in a caked mass having' a vertical stratification, and it is desirable to avoid as much as possible breakage of the sticks and lumps extracted from the oven.

The principal object of the invention is to provide a machine for operating by power the coke-puller, commonly known as the "duckbill scraper, in a manner similar to that by which it is manipulated by hand. To this end the duck-bill scraper may be given a chopping motion for loosening' the coke, a lateral swing in either direction, and inward and outward thrusts to withdraw the coke, and all of these motions and various compound movements resulting from different combinations thereof may be effected by power.

Figure l of the accompanying drawings represents a side elevation of one embodiment of this machine, the engine-cylinders being omitted and several minor parts being' in section, the machine being in position in front of a coke-oven preparatory to drawing the coke therefrom and delivering it into a receiving or coke car opposite the coke-oven. Fig. 2 represents an end elevation thereof, partly in section. Fig. 3 represents a horizontal section of a coke-oven and a top plan, partly in section, of the coke-drawing' machine, the rear end of the cokeway being broken ofi' and a coke-lifter being applied to the coke-puller bar for loosening the coke within the oven preparatory to the withdrawal thereof. Fig. 4 represents, on an enlarged scale, a plan view of the central portion of the machine, pieces being broken out of the bottom of the cokeway of the rotary base below the cokeway and the platform below said base, showing the mechanism for reciprocating the carriage on the car longitudinally. Fig. 5 represents a front elevation, partly in section, of the cokepuller carriage, the supporting-track therefor in dotted lines, the driving-cables, and the grip mechanism on said carriage for grasping the cables. Fig. 6 represents, on an enlarged scale, a perspective view of the lower portion of the mechanism for controlling the various movements of the apparatus, comprising a series of slide-bars, a carriage carrying a multilever, and a plurality of gripping devices connected with said multilevel' and operating on said bars, respectively, parts thereof being broken away. Fig. 7 represents, on a further enlarged scale, a side elevation of a fragment of one of the slide-bars actuated by the multilever, the grip-carriage connected with said lever, and aside elevation ofone of the cams for grippingsaid slide-bar, said cam being in inactive position. Fig. 8 represents, on the same scale, a similar view to that shown in Eig. 7, showing the grip-cam in gripping position. Fig. 9 represents, on a smaller scale, a side elevation of the rotary base constituting a part of the main longitudinally-reciprocating carriage, a longitudinal section of the cokeway mounted thereon and open at both ends, a longitudinal section of the coke-puller carriage adapted to travel over said cokeway, and a coke-pusher swung from the rear end of said coke-puller carriage, the latter moving toward the oven end of the cokeway and the cokepusher riding' over the top of the mass of coke contained therein. Fig. 10 represents a view similar to that of Eig. 9, except that the cokepuller carriage is shown as moving toward the rear end of the cokeway and the coke-pusher as pushing the coke into the coke-car, the front end of said cokeway being closed. l1 represents a view similar to thatof Fig. 9, the coke-puller carriage being shown in full lines as moving' toward the oven and in dotted lines as moving toward the delivery end of the cokeway, the coke-pusher being mounted at the front end thereof and the cokeway being provided at its front end with an inclined closure and at its rear end with a deliveryopening in its bottom. Fig. 12 represents a front elevation of the coke-pusher in the form of a-fork. Fig. 13 represents a front elevation of the coke-pusher composed of a series of independently-swinging tines or fingers. Fig. 14 represents, on an enlarged scale, a plan, partly in section, of the cock for controlling the supply of motive fluid to the engine, the actuating-arm therefor, and a fragment of the slide-bar engaging said arm, parts being broken out and the dotted lines showing four different positions of the arm for regulating the cock. Fig'. 15 represents, on the same scale, a vertical transverse section on line 15 15 of Fig. 14 of the parts shown in said ligure. Fig. 16 represents, on the same scale, a longitudinal section through the boxes for supporting the opposite ends of the various slide-bars controlled by the multilever, the section being taken on a line which shows a side elevation of the end fragments of the slidebar which controls the fluid-supply cock provided with five notches to correspond with the different-positions of said cock. Fig. 17 represents, on the same scale, a plan of a fragment of the reversing-lever-actuating slide-bar provided with a lateral arm and the end of the reversing-lever engaged thereby,the dotted lines indicating two other positions of said parts. Fig. 18 represents, on the same scale, a transverse section on line 18 18 of Fig. 17 of the parts shown in said ligure. Fig. 19represents,

on the same scale, a vertical longitudinal secl tion through the end boxes heretofore referred to under the description of Fig. 16, the section being' taken on a line which shows a side elevation of the ends of the reversing-lever slide-bar, said bar being provided with notches to lock it in three different positions. Fig. 20 represents, on the same scale, a plan of the clutch and slide-bar which control the reversing means of the coke-puller carriage, this slide-bar and clutch being likewise actuated by the multilever and being similar to other clutches and bars actuated by the multilever for controlling the movement of the machinecar and the reciprocation or adjustment of the main carriage which moves longitudinally on said car. Fig. 21 represents, on the same scale, a transverse section on line 21 21 of Fig. 2O of the parts shown in said figure. Fig. 22

represents, on the same scale, longitudinal sections of the end boxes before described for supporting the ends of the various slide-bars actuated by the multilever, the section in this case representing in side elevation the opposide end fragments of the slide-bar which controls'the reciprocation of the coke-puller toward and from the oven. Fig. 23 represents,

on a large scale, a vertical section through a portion of a coke-oven, showing. by dotted lines the coke therein, and a longitudinal section of a coke-loosener on its inward stroke operating to lift the coke from the bottom of the oven and loosen it in vertical stratas preparatory to its removal from the oven by the coke-puller. Fig. 24 represents, on a smaller scale, a section of the coke-oven, the coke therein, and the coke-loosener on its outward stroke along the bottom of the oven.

The same reference-numerals indicate corresponding parts in all the ligures.

The drawings show an arrangement of a coke plant in which coke-ovens, as 1, are disposed in a row or series. A railway-track is disposed on a level or plane 2 in front of the series of ovens, and coke-cars, as 3, travel below the plane 2, substantially parallel with the track on said plane. The machine-car carrying the coke-drawing mechanism travels along the track between the ovens and the track on which travel the coke-cars for conveying away the coke, the track-levels being preferably so arranged that the coke-conveyer of the cokedrawing machine may take the coke from the door of the oven and discharge it into the tops of the coke-cars. In this operation there is no handling of the coke between the drawing thereof from the oven and its discharge into the train of coke-cars.

A car traveling on the track adjacent to the ovens and hereinafter called the machinecar supports the coke-drawing mechanism. This car has preferably a skeleton frame comprising two longitudinal side rails 10 and 20, composed, preferably,of U-shaped angle-bars, disposed on their sides and resting, respectively, on journal-boxes supported on car-` axles 3() and 40. These side bars have their open faces tow'ard each other and are connected by cross-bars 15 and 25 and other suitable braces.

The coke-drawing mechanism is preferably mounted on a carriage adapted to move longitudinally on the machine-car for the purpose hereinafter described. This carriage in its preferable form comprises a traveling platform 50 in skeleton or other construction and a rotary or swiveling base 60, adapted to turn thereon. The platform 50 is preferably circular and provided on its under side with dependent lugs 51 and 52, carrying flanged wheels which travel in the recess of the side rail 10, and with dependent lugs 53 and 54, carrying flanged wheels which travel in the opposite side rail 20. The platform is also provided with a central hub 55 and with a circumferential upward flange 56, provided on its inner periphery with a circular rack 57, as clearly shown in Fig. 2.

The swiveling base 60 is preferably provided on its under side with a circumferential downward iiange 61, preferably provided with antifriction-rolls, which are journaled in recesses in said flange and adapted to travel on IOO ITO

center with horizontal shaft-bearings 63 and (3-1 (shown iu dotted lines in Fig. et) and with y a recess (5:3 tangent to a circle near the center. as shown in Figs. 1 and 4 and for the purpose hereinafter described.

The coke-drawing mechanism and the driving engine or motor are mounted on the swiveling base 60. and the support shown therei for comprises four sills TO and 71,72 and 73. as shown in Figs. 1, Q, and the sills TO and T1 being' disposed on opposite sides of the center of the base and projecting` parallel to each other beyond the periphery thereof and the sills TQ and T3 being similarly disposed relative to each other on the other side of the center of the base and in line with the sills and T1. respectively. The sills TO and T2 are connected at their inner ends by a short connecting-sill T-1 and the sills 71 and T3 are likewise connected at their inner ends by a short sill 75. These sills project sufiiciently from opposite sides of the base to extend from the front line of the ovens on one side of the machine-track to the line of coke-cars for receiving the coke on the other side of said track. The sills T0 and T2 are provided at their outer ends. respectively. with upright standards T6 and TS, which are made integral therewith or attached thereto, and the sills 71 and T3 are provided at their outer ends. respectively, with correspond ing upright standards TT and 79. A track for a reciprocating coke-puller carriage is supported on these standards and preferably comprises a U-shaped rail 80, disposed on the standards 76 and 78. and a U-shaped rail S5, disposed on the standards TT and 79. These rails have their open faces toward each other and form ways in which the coke-puller carriage travels. The rail 80 is provided on its rear end with an upright arm 81, having at its upper end a tripping-cam S2, for the purpose hereinafter described, and the rail is provided at its opposite ends with standards S6 and 8T and with a central standard SS. having' a sprocket-chain guide 89, for the purpose hereinafter described.

A coke-puller carriage of any suitable con- `struction is adapted to reciprocate by any suitable means on the track 80 85 toward and from the oven. This carriage preferably comprises a traveling platform and a rotary table 110, adapted to turn thereon, the platform being provided with a central stud 91 and the table with a tubular boss 111, adapted to receive said stud, as shown in Fig. The platform 90 is preferably rounded at its front end and provided atits rear end with an extension 92. which affords ample standing i room for the engineer. This platform is provided underneath on opposite sides with lonscraper at different angles, as desired.

gitudinal angle-bars 93 and 9-1 parallel with each other. as shown in dotted lines in said figure. These angle-bars are provided with outwardly -projecting ljournal-studs having flanged wheels which travel in the U-shaped rails 80 and 85. These angle-bars are provided at their opposite ends with plows 95, 96, 9T, and 98. which serve to clear said rails of any coke which may bel lodged therein. Brackets or boxes 10() and 101 depend from this platform ou opposite sides thereof and serve as supports for cable-grips. hereinafter described. A dependent bracket 102 extends below the bracket on the near side and serves asa support for the multilever and it gripper-s, hereinafter described. which act on a series of slide-bars for different actuating mechanisms. This platform is provided on the far side of its extension 92 with an upright standard 103. (shown in Figs. 1. 2, and and on its under side with a circular rack 10-1. preferably somewhat smaller in diameter than the table 110.

The rotary table is provided with a downward circumferential flange 112. which is preferably provided with antifriction-rollers which travel on the platform 9o when the table is rotated. A vertical shaftbearing 11?) is mounted on the rotary table, and a shaft 114 is journaled therein and extends below said table and is there provided with a pinion 115, which meshes with the circular rack 101 attached to the platform 91). This shaft is provided at its upper end with a handwheel 116. which is actuated by the operator to turn the table to any desired position.

The coke-puller proper is mounted on the coke-puller carriage in such a manner as to be swung vertically and oscillated axially by mechanical means. the lateral movement being obtained by the swiveling of the rotary table 110 or of the main base 6() or both. Two standards 11T and 1.18 are mounted on the rotary table 110 parallel with each other on opposite sides thereof. A vertially-oscillating coke-puller socket 12() is provided with trunnions 19.1 and 122,' iournaled in bearings at the rear of said standards, and in rear of said trunnions with a counterweight 1223. A cokepuller bar 130 is supported at its rear end in said socketand provided at its front end with a detachable coke-loosener or with a cokepuller which is interchangeable with the cokeloosener. The coke-puller bar extendsslightly beyond the rear end of the socket and carries a supplemental counterbalaneing-weight 131. Means are provided for axially oscillating' the coke-puller bar to adjust the coke puller or Any suitable means may be used for this purpose. The means shown comprise two ratchet-wheels 132 and 133 [ixed on the rear end of said bar, the teeth of said' wheels being oppositely disposed relatively to each other. A lever 110 is provided at its inner end with an eye or col- TOO ISO

lar 141, which turns loosely on the bar 130 betweenA the ratchet wheels 132 and 133. Spring-pawls 134 and 135 are pivoted on said lever and engag'e said ratchet-wheels, respectively, on the swing'ing of the lever in either direction. The lever 140 is provided on opposite sides of its handle end with lugs, to which angular levers 142 and 143 are pivoted. The angular lever 142 is connected by a connecting-rod 144 with the pawl 135 and the angular lever 143 is connected by a rod 145 with the pawl 134. An indicator 136 in the form of an arrow or otherwise is attached to the counterweight 131 or otherwise connected with the bar 130 to show the position of the coke-puller within the oven under or in contact with the coke. This indicator is preferably adjusted to project from the cokepuller i bar at the same angle that the coke-puller projects. A swing' of the lever 140 toward the right, as shown in Fig. 2, will cause the pawl 134 to engage the ratchet-wheel 132 and the coke-puller bar will be oscillated on its axis in the same direction a proper distance to bring the coke-puller at the end thereof to the desired angle, the other pawl, 135, moving' with its ratchet-wheel without action thereon. A

swing of the lever toward the left will cause the pawl 135 to engage the ratchet-wheel 133 and turn the bar and coke-puller in the opposite direction, the pawl 134 being' in this instance inoperative. When it is desired to tu rn the coke-puller bar through an are greater than will be imparted thereto by a single convenient swing of the lever 140, one of the angular levers 142 or 143 is grasped in conjunction with said lever and the actuating-pawl is lifted out of contact with its ratchet-wheel while the lever is swung back to take a new grip. ln this way the coke-pullerY bar 130 may be oscillated in either direction through three hundred and sixty degrees, more or less,

as necessary. Means are provided for locking the lever 14() in three permanent positions. The means shownr comprise a locking-plate 124, which may be in the form of a flange on the counter-weight 123. This locking-plate forms a semicircula r arc provided with a notch 125 at its top and two opposite side notches 126 and 127 near its base. A spring-actuated bolt 146 is mounted on said lever and controlled by an angular lever 147, said bolt being' adapted to ride on the periphery of the locking-plate 124 to engage any of its notches when the lever is swung into position to cause the bolt to reg'- ister therewith. The coke-pullcr bar 130 is designed to carry at its outer end either a lift ing coke-loosener or a coke-puller, the latter being' preferably of such construction as to adapt it for use either as a claw or as a scraper for the coke. The lifting' coke-loosener and cokepuller are detachable from the cokepuller bar and are designed to be used interchangeably and in succession, the coke-loosener operating `to loosen the caked coke and the coke-puller to claw and withdraw the loosened coke.

The particular form of lifting coke-loosener 150 illustrated in the drawings comprises a convex or inverted-dish-shaped body 151, pro' vided with a radial shank 152, said shank having a shoulder 153 and a slot 154, as shown in Figs. 3, 23, and 24. A wedge-shaped orl other key 155 is adapted to pass through slots in the outer end 'of the bar 130 and through the slot 154 in the shank of the coke-loosener, whereby the latter is locked to said bar. Any other suitable means for attaching the scraper may be employed.

The coke-puller 160 is preferably7 similar in form to that commonly used in hand cokepulling and known as a duck-bill cokepuller, consisting' of a single elongated prong or claw 161 and a shank 162 at right ang'les to the claw, or thereabout, said shank being also provided with a shoulder 163 and with a slot 164, as shown in Fig. 1. The body of the shank is adapted to tit within the outer end of the bar 130 down to the shoulder 163, and the key 155 or other means is used for locking the puller in position on the puller-bar. The slot in the shank of the loosener is preferably in a horizontal plane with reference to th'e body thereof, so as to avoid contact of the key with the bottom of the oven, and the slot in the shank of the coke-puller is preferably in line with the claw, so that when the latter is turned on its side and used as a scraper the key will not come in contact with the bottom of the oven. The shanks of the coke-loosener and coke-puller are made to tit loosely in the socket end of the coke-puller bar to provide for expansion under the heat of the oven.

Means are provided for swinging the cokepuller bar in a vertical plane to cause the cokeclaw to rise and fall to engage the coke within the oven. These means are preferably such as are within easy reach of the operator and when constructed as herein shown comprise a yoke 170, disposed between the standardsl 117 and 113 in front ot' the bearings for the trunnions of the oscillating socket which `carries the coke-puller bar 130. This yoke has trunnions on its opposite sides which engage bearings in the front portions of said standards, and it is provided with crank-arms 171 and 172, which extend parallel with the cokepuller bar on opposite sides of the front portion'of the oscillating socket. These crankarms are provided at their outer ends with inwardly-projecting crank-pins 173 and 174, which engage longitudinal guideways 128 and 129 in opposite sides of the front portion of the oscillating socket 120, as shown in Figs. 1, 3, and 5. A lever 175` herein called the clawing-lever, is secured to one of the trunnions of the yoke 170. A locking-plate 176 is attached to the standard 117 and provided with notches 177 and 178, and the clawinglever is provided with a spring-actuated bolt IOO IIO

179, adapted to ride over said locking-plate, and with a bell-crank lever 179' for releasing the bolt. By oscillating' this clawinglever the operator can easily swing' the counterweig'hted coke-puller bar and raise and lower the coke-puller and perform a clawing operation.

A cokeway or chute 18() is disposed beneath the track 8O 85 and extends from end to end thereof, and the coke drawn from the oven on one side of the machine is pushed through this chute into the coke-cars on the other side thereof. This cokeway is preferably rectangular in cross-section and composed of heavy sheet metal. It rests at its bottom on the sills mounted on the swiveling base GO. The upperedg'es of the sides of the cokeway are provided with outward flanges which are secured to the under surfaces of the rails 8O and This cokeway may be open at both ends and along its top. Uprig'ht wing's 181 and 182 (shown in Figs. 1 and 3) are preferably disposed on opposite sides of the front end of the track `from which the cokeway is suspended and project above the oven-hearth on opposite sides of the oven-door and serve as guides to direct the coke withdrawn through the door into the cokeway below. Means are provided for pushing' the coke through the cokeway. The means shown for this purpose consists of a pusher 190, attached to the reciprocating' cokepuller carriage and adapted to shove the coke through the cokeway 18() from the front end thereof and deliver it at the rear end thereof into a coke-car. This pusher is preferably hinged to one end of the platform 90 ofthe coke-puller carriage and is preferably adapted to swing freely in a vertical plane from an active vertical position to an inert horizontal position. The pusher may be in the form of an apron, as shown in Figs. 2, 9, and 10, or in the form of a comb 191,as shown in Figs. 11 and 12, or in the form of a series of independentlyswinging fingers 192, as shown in Fig. 13. Stops, as 193, serve to prevent the apron from swinging forward beyond a vertical plane in its down position. As the coke-puller carriage moves toward the oven to grasp a. charge of coke therein the coke-pusher rides freely over any coke that may be contained in the cokeway, and as said carriage moves backward the end of the coke-pusher is thrust downward into the mass of coke, as indicated in dotted lines in Fig. 9, and pushes the coke behind it along' the cokeway and over the outer end thereof into the coke-car, as shown in Fig'. 10. The coke-pusher is shown as pivoted to the rear end of the platform of the coke-puller carriage in Figs. 9 and 10 and to the front end thereof in Fig. 11. In the form shown in Fig. 13 separate fingers may swing independently of others in passing over large lumps. The cokeway 180 may be provided at its front end with an inclined bottom 183, as shown in Fig. 11, down which the coke slides into the trough as it is drawn from the oven. The cokeway may be provided at its rear end with an opening' 184 in its bottom, as shown in Fig. 11, through which the coke may fall into the car as it is shoved through the cokeway by the pusher, in which case the track for the coke-cars will preferably be in such relation to the coke-puller that the coke discharged through said bottom opening will fall into the coke-cars located immediately under said opening.

A motor for driving the machine-car and the various mechanisms comprised in the cokedrawing apparatus is mounted on the swiveling base 60. This motor may be actuated b V electricity, steam. air, o1' other motive Huid. The drawings illustrate a duplex compressedair engine 200, having' a driving crank-shaft 210, which projects at its opposite ends beyond its supports in the engine-frame. This drivingshaft is provided with means for transmitting' motion to the various mechanisms of the apparatus which are driven by power. The driving mechanism for causing the machine- 'ar to travel along' the track from oven to oven comprises a beveled gearwheel 220, loose on said driving-shaft. This beveled wheel 220 meshes with a beveled gearwheel 221, which is integral with or constitutes a Hange upon a cog-wheel 222, which rotates on a vertical stud 223 on the bed-plate of the engine, as shown in Figs. 1 and t. This cog-wheel 222 meshes with a larger cog-wheel 221, which is fixed on a hollow shaft 225, which extends downward through the axis of the swiveling' base. This hollow shaft is provided at its lower end with a beveled gear 226, which meshes with a sliding beveled pinion 231, disposed on a longitudinal shaft 230, journaled in the cross-bars 15 and 25. A yoke 227 is suspended on the beveled gear-wheel 226 and provided at one end with a dependent collar 228, which engages the g'rooved end of the sliding' pinion 231, and at the other end with a dependent guide 229, which slides on the shaft 230. The longitudinal shaft 230 is provided with a longitudinal groove 234, and the sliding' pinion 231 is provided with a spline which eng'agcs said groove and causes the shaft and pinion to rotate together. A beveled pinion 232 is lixed to the shaft 230 at one end thereof and meshes with a beveled pinion 23;) on the car-axle 30. By this mechanism motion is communicated from the drivingsha'ft of the engine to one of the axles and the machine is made to travel along' the track in either direction according to the direction of motion of the engine controlled by the reversing-valve. Any suitable means may be employed for switchingl this mechanism into operative connection with the driving-shaft. The means herein shown for this purpose will be hereinafter described.

The means for reciprocating the carriag'e carrying the coke-drawing mechanism longi- IOO IIO

tudinally along the machine-car for the purpose of enabling the coke-puller to operate obliquely to gather coke from the sides of the oven comprises when constructed as shown in Figs. 1, 2, and 4 a gear-wheel 240, loose on the driving-shaft 210 and meshing with a corresponding gear -vvheel 241, attached to a sleeve disposed on a lateral stud projecting from one of the engine-standards. This sleeve is provided at its outer end with a sprocketwheel 242, and a sprocket-chain 243 connects the latter with a sprocket-pinion 244 on a worm-shaft 245, which is journaled in the bearings 63 and 64 on the swiveling base 60. This worm-shaft has a worm 246, which meshes with a worm-wheel 247, attached to the upper end of a tubular shaft 248. This tubular shaft extends downward through the center of the swiveling base 60 and traveling platform 50 and surrounds the hollow shaft 225 heretofore described, and it is provided at its lower end below the platform 50 and above the crown-wheel 226 with a gear-wheel 249. Alongitudinal rack-bar 250 is supported on brackets, as 251 and 252, attached to the side rail 10 of the car-truck, and extends longitudinally thereof, and this rack is engaged by said gear-wheel 249. Means are provided, conveniently located for manipulation bythe operator, to switch this mechanism into and out of gear with the driving-shaft, which means will be hereinafter described.

Any suitable mechanism for rotating the swiveling base 60 may be used.

This clutchsleeve is splined on said shaft and provided with teeth which engage corresponding clutch-teeth on the hub of the beveled gearwheel 220, which is loose on the driving-shaft. This slide-bar is provided with two not-ches 423 and 424 at its opposite ends, which are engaged by the spring-dogs 383 and 384, as shown in Fig. 22, for holding' the bar in two positions, one for effecting the engagement of the traction mechanism and one in which said mechanism is disengaged or thrown out of gear, as shown in Fig. 22.

The slide-bars 430 and 440 are similar in construction to the slide-bar 420, the slide-bar 430 operating a clutch 431 for clutching and unclutching the gear-wheel 240, which drives the mechanism for longitudinally reciprocating the lower carriage, and the slide-bar 440 operating a clutch 441 for clutching and unclutching the beveled gear 290, which transmits motion to the cables for driving the cokepuller carriage.

The multilever 450 for operating the various actuating slide-bars just described is pivoted on a post 103, attached to the bracket 102, which depends from the coke-puller carriage. This lever, which is shown in Figs. 1, 2, and 3 and on a large scale, with its upper part broken olf, in Fig. 6, is provided at its upper end with a cross-bar 451, carrying a plurality of handles, as 452, 453, 454, 455, and 456, and at its lower end with lateral studs 457 and 458. The lower end of the bracket 102 is provided with horizontal arms 104 and 105, and guideways 106 and 107 are disposed opposite each other on said bracket and arm. A grip-carriage 460, provided with ribs 461 and 462 on its opposite sides, is adapted to slide in said guideways and is provided on its upper surface with slotted lugs 463 and 464, which are engaged by the studs 457 and 458 at the lower end of the multilever. This gripcarriageis provided with a plurality of flanged guideways, like 465, disposed side by side, through which the various slide-bars 400, 410, 420, 430. and 440 pass. The top of the gripcarriage is provided with aseries of slots just above the several slide-bars, and a transverse rod 466 extends across the carriage above said slots through lugs, as 467, interposed between the cams. Aseries of cams 472, 473, 474, 475, and 476 are pivoted on said transverse rod and provided with. tails which swing in the top slots aforesaid and severally engage the respective slide-bars when the cams are swung in upright position (see Fig. 8) and release said slide-bars when the cams are swung into horizontal position. The cross-bar 451 of the multilever 450 is provided with a rod 459, and a series of angular or bell-crank spring finger-levers 482, 483, 484, 485, and 486 are pivoted thereon. A series of connecting-rods 492, 493, 494, 495, and 496 connect the spring linger-levers 482, 483, 484, 485, and 486 with the cams 47 2, 473, 474, 475, and 47 6. Whenever the operator wishes to actuate any of the slide-bars, he grasps the handle and finger-lever of the multilever, which is connected with the cam disposed over that particular slidebar, and thereby operates the mechanism controlled by the latter. For instance, the grasping of the finger-lever 483 causes the cam 473 to engage the'slide-bar 410 and clamp it tightly against the J[langes of the guideway 465, as

lOO

shown 'in Fig. 8, and while the slide-bar is so clamped a swing of the m ultilever 450 in either direction will cause the carriage 460 to move in the opposite direction and carry the slidebar with it. Thus a movement of the slidebar 410 toward the right in Fig. 4will swing the reversing-lever 340 into either of the dotted-line positions there shown.

Operation: The operation of the machine will now be described. The machine-car is brought into position opposite the oven, to be drawn by means of a separate locomotive or by its own traction mechanism. In the latter case the flexible pipe-section 362, of sufficient length to reach from one oven to another, is connected at one end to the air-main 360 and at the other end to the coupling 356. Then the multilever 450 is grasped by the handle 452 and finger-lever 482 and the cam 472 made to grip the slide-bar 400, and then by a slight swing of the multilever said slide-bar is shifted and the fluid-supply cock 370 is opened. Then the multilever 450 is actuated by the handle 454- and finger-lever 484, and the cam 47 4 made to grip and move the slidebar 420, whereby the clutch-sleeve 422 is shifted and the traction mechanism is thrown into gear and the machine made to travel to the required point. Then the operator grasps the hand-wheel 271 and by it turns the swiveling base 60 a quarter-rotation, bringing' the cokeway at right angles to the machine-car and into position to receive the coke from the oven and deliver' it into the coke-car 3, as shown in Fig. 1. Another manipulation of the multilevell 450 by means of its handle 456 and finger-lever 486 shifts the slide-bar 440 and throws the clutch 441 into connection with the gear 290, whereby motion is imparted to the endless cables, the engine then moving in forward direction and causing the upper runs of said cables to move toward the oven. Then the grip-lever 320 on the coke-puller carriage 110 is actuated to bring the cable-grip mechanism mounted on said carriage into gripping' connection with said cables. The coke-puller carriage is thus made to travel toward the ovens, whereby the coke-puller160 or cokeloosener 150 is thrust through the door thereof. The coke-loosener 150 is preferably first applied to the coke-puller bar 130, and as the coke-puller carriage moves toward the oven this coke-loosener slides along' the bottom thereof underneath the caked coke within the oven and has a wedge-like action, lifting' a strip of coke equal to the width of the cokeloosener and breaking it from the mass of coke on either side thereof, as shown in Fig. 23. The coke-puller carriage is caused to move toward the oven until the coke-loosener enters to a point near the back wall thereof, as indicated in Fig'. 3. Then the operator operates the multilevel 45() by its handle 453 and finger-lever 483, whereby the slide-bar 410 is moved and the reversing-valve of the engine is shifted, the motion of the cables 288 and 289 reversed, and the coke-puller carriage caused to travel rearward, withdrawing the coke-loosener, as indicated in Fig. 24. Then the multilevel' is actuated by its handle 455 and finger 485 to shift the clutch 431 into connection with the gear-wheel 240, whereby the main platform 50 may be shifted first in one direction and then in the other on the cokecar, as indicated in dotted lines in Fig. 3, and the coke at both sides of the oven loosened by inward thrusts of the coke-loosener, as before described. Then the coke-loosener is removed from the coke-puller bar 130 and a duck-bill or other coke-puller 160 is applied thereto. Then the engine is caused to move forward, and the coke-puller carriage is again made to travel toward the oven and the coke-puller thrust thereinto a distance sufiicient to make a first drawing of the coke. Then by means of the lever 175 a pickax or clawing motion may be imparted to the coke-puller, and by the lever 140, assisted by the angular fingerlever 142 or 143, a lateral swing may be imparted thereto in either' direction. Then the reversing-lever is again actuated and the engine made to move backward, whereby the coke puller carriage withdraws the cokepuller -and the coke in front thereof, the latter sliding to the door and falling into the cokeway 180. Then another thrust of the coke-puller is made into the oven, two or more thrusts being required to take out the coke in a straight line through the diameter of the oven. Then the main carriage is oscillated first in one direction and then in the other on the coke-car and moved longitudinally thereon, as indicated in dotted lines in Fig. 3, and the coke at the sides of the oven is withdrawn by inward and outward thrusts of the cokepuller through the reciprocation of the cokepuller carriage. The lateral strokes of the coke-puller may also be effected in a measure by swiveling the table 110 by means of the hand-wheel 116. The coke-puller may thus be made to simulate the action of hand cokepulling, and the coke may be withdrawn without breakage of the sticks thereof.
